Piston to bore clearance with forged pistons?

What would be the normal bore to piston clearance on a Impreza using Omega forged pistons? My engine was built 15k miles ago by Autosportif as a fast road with occasional trackday use. I will be taking the engine out next week and evaluating the condition before the next stage of mods,what sort of clearances would i be looking at ?

regards mark

Autosportif should have a spec sheet of the the engine build - best to ask them or a call to RCMS to see what the manufacturers spec is.
Ball park figure of 0.003" piston/bore clearance for forged pistons but that is dependant on make of piston and intended use eg road use/track/ etc etc.
